Basically most casinos has the right to ask document like that, but most other casinos implement like leveling KYC. When it comes to source of funds document, it is the highest level of KYC and afaik it is rare to be asked. For normal gamblers who gamble recreationally and deposit/withdraw normal amount (not that huge), I think they wont be asked to provide source of funds document. Looking at the above issue by brassnuts, it seems that this casino do not serve him fairly and seems to be trying to delay the withdrawal as long as possible (hopefully I'm wrong) as I hope brassnuts will get his money as soon as possible.
Yes, they do have the right to request documents for the verification process. But if you ask for a passport and source of funds documents, that is very rare and I have never found one. Maybe a passport can be requested too but as for the source of funds, that's very rarely asked.Ordinary gamblers who don't gamble very often and only with small amounts of money won't think much about verification. They won't want to spend a lot of money because it could cause problems for them. They are better off continuing to gamble with just enough money.
Yes, we hope he can get the money. We all also have to be careful when gambling.
